Is this your sister? 英语语法

来源：百度知道编辑：UC知道时间：2024/05/09 18:58:03

Is this your sister? No,it isn't.
Is that your brother? Yes,it is.

为什么这里的“your sister”、“your brother”在回答时要用“it”代替？可以用“she”或“he”代替吗？

可以，
当用this（that）来问问题时，要用it回答
同样地，these（those）出现在问题中时，用they来回答

可以

只能用“your sister”、“your brother”,不能用“it”。

英语里有时候不知道是谁的时候会用it而不用he/she 比如大电话不知道对方是谁就说 who is it

Is this your sister What is your sister like ? what is your sister and you doing? is this your business 是什么意思 Is this your bedroom? ______ How is your sister 应该怎么回答?(英语口试) Are your sister Mary Cooper? Yes,she is.错哪里? _girl is your sister ? The one in red. 现在进行时：your sister is--------（read,reading). If your uncle's sister is not your aunt, who is she?
